As opposed to doing an article on this, I am going to post my progress here as I go. If there continues to be interest, I will continue.

This shows the parts used to assemble my switch block. I used a plastic protector cover that was on an inkjey cartridge. Made 5 holes in it for the toggle switches and cut out a section for a 4-position DIP switch to be mounted. I then wired it using some wire from a data cable and hot-melt glued the cable in place.
The toggle switches use a center-off feature to avoid to outer most connectors from ever being connected together. (Shack model #275-325) I'll do a drawing later to show how it is wired. These toggle switches were used because I have been unsuccessful in finding something called a tri-state 8-position DIP switch. There are millions of them in the UK, but so far noone in the US has them, and I don't want to order 500 of them!!

With the moderators permission, I will also post links to the various articles from which I gathered much help. For me it began with this post LINK
and you can find all the other links from there.

Well, I couldn't wait any longer. Spent several hours this afternoon installing the switches.
Initially it wouldn't work but I found out the L1s on the CPU came open due to my previous attempt at cutting bridges, which didn't work!!
Anyway, I am testing with a T-Bird 1 gig and 11x and 12x boot up with no problem.
Gotta take a break now and do some more testing later.

Well, it is a "B" bird so the default FSB is 100 MHz.
It won't do 1596. That is a little beyond what this one will do.
To give you an idea, here are some numbers.
@10.5x it will post at 138FSB and 143 FSB but not at 147
@11x it will post at 133 and 138 but the OS will not load at 143
@12.5 it will post at 110 and 112 but not 124
( this is where I figure the limit is since it will run at 1500 but not 1550)
So, it seems to have a limit of about 1500 MHz, which is what I usually ran it at without the multi-mod, 10x150 FSB

I mainly did this mod to see what my XP1700 will do, but I need to unlock it first.

maxima88 is very correct. Lots of it and very tiny places too.
Also, keep in mind that THIS WILL VOID ANY WARRANTY ON THE MAINBOARD!!

BTW, I unlocked the cpu using correction fluid for filler and conductive paint for the bridges. Took 3 tries to get all of them connected correctly. In the process, I scratched through the surface to the copper under the green stuff. It is very soft and easy to mess one up if not very careful.
